Description

Household appliance with user interface
Technical Field
The present invention relates to a household appliance having a user interface for visualizing control information and for inputting instructions for controlling the operation of the household appliance.
Generally, the present invention relates to a home appliance including:
-a housing confining a treatment seat adapted to receive and/or support one or more household products (linen, crockery, food, furniture surfaces, textiles) in a treatment position to subject it to a desired treatment;
-one or more treatment devices arranged within the housing, the treatment devices being actuatable to perform one or more specific treatments in a treatment position;
-one or more treatment detector devices arranged within the housing and configured to detect one or more values of a treatment parameter of a treatment to which the household product is subjected in the treatment position;
-optionally, one or more anomaly detectors arranged within the housing and configured to detect one or more operational anomalies of the household appliance;
an electronic control system arranged in the housing and in signal connection with the processing means and the processing detector, and configured to control the processing means according to the processing program and according to the values detected by the processing detector;
a user interface in signal connection with the electronic control system to allow a user to select (parameters of) a treatment program of the household product and for visualizing the selected and/or running parameters of the treatment program.
Background
In prior art household appliances, the user interface is formed in one or more fixed positions of the casing or of the treatment seat (refrigerator) and comprises one or more buttons or knobs or capacitive touch sensors, and possibly a visual indicator, such as a warning light or a liquid crystal display (TFT) or an OLED.
The user interfaces of household appliances of the prior art are satisfactory when the development of strategies and processing parameters, OSD, communication data and electronic controls and the development of processing devices, the evolution of the design of the appliance casing, and the average service life of the appliance are carried out synchronously.
In the current state of the art, household product processing strategies, electronic control and data communication technologies, the amount of processing data and parameters available and possible for controlling household appliances, and the aesthetic design of household appliance housings are rapidly evolving and, frequently, one conflicts with or "lags" the other.
One reason for dissatisfaction with known household appliances is the inability to provide a user interface that is large enough and extends to display large amounts of process control information without causing spatial interference with other components of the household appliance.
Another reason for dissatisfaction with known household appliances is the conflict between the need for a flat and extended housing surface to position the liquid crystal display (TFT) or OLED and the desire for innovative designs for appliances with curved surfaces and freely definable color and surface structure.
Another reason for dissatisfaction with the known household appliances is the conflict between the need to have very large openings and access doors or ports (the relatively small outer dimensions being the same) in order to fit the household products into the household appliance and the need to provide free space for mounting the user interface, usually on the same front wall of the appliance.
Another reason for dissatisfaction with the known household appliances is that the specific concept of the user interface must now be designed in close connection with the specific items of the household appliance and its external design, making it difficult to transfer the new concept of the user interface to the pre-existing household appliance, which one wishes to maintain or be another type of household appliance with a different external shape.
Disclosure of Invention
It is therefore an object of the present invention to provide a household appliance with a user interface having features that avoid at least some of the disadvantages of the prior art.
Another object of the present invention is to provide an appliance with a user interface having features that can be easily adapted to the household appliance by means of a non-continuous surface, for example in the presence of moving parts (access ports, doors, detergent drawers) and/or non-planar parts, and that can be applied and transferred between housings with different aesthetic designs, with versatility in terms of display size, information to be visualized and input instructions to be allowed.
These objects and others are achieved by a household appliance having a user interface. The household appliance comprises: a housing having an outer wall forming an outer surface of the household appliance; a treatment receptacle formed in or on the housing and adapted to receive or support a household product in a treatment position; at least one treatment device arranged within the housing and causing a treatment to be performed at the treatment location and subjecting the household product to the treatment; at least one process detector disposed at least partially within the housing and configured to detect a value of a process parameter of the process performed by the processing device; optionally, at least one anomaly detector disposed at least partially within the housing and configured to detect a magnitude indicative of an operational anomaly of the household appliance; an electronic control system arranged in the housing and in signal connection with the processing device and the processing detector, and configured to control the processing device in accordance with a processing program and in accordance with values detected by the processing detector; a user interface in signal communication with the electronic control system, the user interface comprising: instruction insertion means for inputting an instruction for selecting a parameter of the processing program and for inputting an instruction for executing the processing program; and a display device visualizing selectable parameters of the treatment program and visualizing treatment parameters during implementation of the treatment program, wherein the display device comprises at least one video projector mounted to the household appliance at the outer wall and configured to perform visualization by means of a process of light projection on a display area of the outer surface of the housing, and wherein the instruction insertion device comprises at least one instruction input sensor adapted to detect a movement of a user's hand at the display area and to generate a corresponding hand movement signal, wherein the electronic control system: processing the hand movement signal and generating a user instruction signal; setting parameters of the processing program according to the generated user instruction signal; commanding display by means of the video projector according to the generated user instruction signal.
According to one aspect of the invention, the display means of the user interface comprise at least one video projector mounted at its outer wall on the household appliance and configured to perform visualization by means of the process of light projection on the display area of the outer surface of the casing.
The visualization performed by means of light projection allows the user interface to have a display area that is large enough and extended to visualize a large amount of process control information, without any spatial interference to the various components forming the outer surface of the household appliance.
The visualization performed by means of light projection also allows visualization on interrupted surfaces or surfaces consisting of areas of different structure and/or color as well as on non-planar surfaces and thus allows innovative aesthetic designs of household appliances with curved surfaces and freely definable colors and surface structures.
The visualization performed by means of light projection also allows very large openings and access doors or ports for the treatment of the load of household products, without the need to provide additional space dedicated to the visualization, which is possible at least partially on the same access door (for example in the case of ovens, refrigerators, dry cleaners or dishwashers/dryers) or even on the treatment seat (for example in the case of cooking tables or ironing boards) if the latter forms part of the outer surface of the casing.
The video projector may be at least partially concealed by the housing and its dimensions are not dependent on the size or direction of the light projection performed. This facilitates the transfer of user interface concepts between home appliances having different exterior designs.
According to another aspect of the invention, the user command insertion means comprise at least one command input sensor adapted to detect the positioning and/or movement of the user's hand at the display area, and the electronic control system comprises association means which:
associating the detected position and/or movement of the hand with an instruction input field visualized in the display area by means of a video projector (e.g. buttons, knobs, virtual sliders), and
-generating a corresponding command input signal.
The electronic control system is configured to set a process parameter based on the generated command input signal.

Detailed description of the display area 15 of the outer surface 4
According to one embodiment, in the areas of the outer surface 4 intended to be visualized by projection of light, the outer surface 4 is colored and treated so as to have a higher light reflectivity with respect to areas not intended to be visualized.
According to another embodiment, in the display area 15, the outer surface 4 may be continuous or discontinuous, for example formed by components of the appliance 1 connected to each other, without the outer surface and/or the moving components being mutually discontinuous.
According to one embodiment, the outer surface 4 may be planar or non-planar, e.g. curved, in areas of the outer surface 4 intended to be visualized by projecting light.
According to one embodiment, the household appliance 1 comprises a door 18 for closing the treatment socket 5 during the implementation of the treatment program, and the display area 15 may also extend at least over the portion of the outer surface 4 formed by the door 18.

According to one embodiment, the housing 2 of the appliance 1 forms an auxiliary access opening for one or more accessories of the treatment device 7 (e.g. detergent drawer, powder bag, filter, condensate collection drawer) which is closed by an auxiliary lid 19 during the implementation of the treatment procedure, and the display area 15 can also extend at least over the portion of the outer surface 4 formed by the auxiliary lid 19.
Detailed description of the video projector 14
According to one embodiment, the household appliance 1 comprises a single video projector 14.
According to another embodiment, the household appliance 1 comprises a plurality of said video projectors 14 configured to project light on one and the same display area 15 and/or on a plurality of said display areas 15 which are different and at a distance or adjacent to each other.
The respective video projectors 14 may be located on two opposite or different sides of the display area 15 and project in opposite directions or in different directions to avoid shadows when the user's hand approaches the display area 15.
In the case of multiple light projections on the same display area, video projector 14 is configured and controlled by electronic control system 10 such that the light wavelengths and/or illumination frequencies are compatible and do not imply destructive interference of the projected light.
According to one embodiment, the electronic control system 10 or the video projector 14 comprises an anti-distortion device configured to calculate and generate a pre-distorted image to be projected, for example by means of a rectangular to trapezoidal pre-distortion, for example from rectangular to trapezoidal, of the image projected on the outer surface 4 in the opposite direction with respect to the oblique projection, due to the inclination of the light cone and the projection axis of the video projector 14 with respect to the outer surface 4 in the display area 15.
Pre-distortion of the image occurs according to the projection cone angle and the tilt angle of the projection axis of the video projector 14 relative to the outer surface 4 of the display area 15 to compensate for the projection distortion. In this way, it is possible to obtain a projected image having a rectangular or circular or elliptical profile that is symmetrical with respect to two perpendicular symmetry axes, for example.
According to an embodiment, the one or more video projectors 14 may include one or more of the following video projectors:
LCD video projector (LCD video projector)
DLP video projector (micro-mirror video projector)
LCoS video projector (liquid crystal on silicon)
D-ILA video projector (digital direct drive image light amplifier)
SXRD video projector (silicon crystal reflective display)
An LP video projector (laser video projector), for example monochrome,
DLP video projector (digital light processing)
Particularly advantageously, in order not to interfere with the aesthetic design of the casing 1, the video projector or projectors 14 are configured as mini-projectors or mini-projectors.
According to one embodiment, the video projector 14 is located entirely within the housing 2 and on the inner side 20 of the outer wall 3, and performs light projection through a window 21 formed in the outer wall 3. The window 21 may be a through opening or be protected by a protective wall 22, which protective wall 22 is transparent and/or openable and closable by means of a protective cover 23 and/or by means of a louver 24. This allows hiding and protecting the video projector 14.
According to one embodiment, the video projector 14 includes: an inner part 25, which is located completely within the housing 2, i.e. on the inner side 20 of the outer wall 3; and an outer part 26 which is located completely outside the housing 2, i.e. on the outside of the outer wall 3, wherein the volume of the inner part 25 is larger than the volume of the outer part 26. This reduces the visual impact of the video projector on the aesthetic appearance of the household appliance.
According to one embodiment, the video projector 14 is supported in a concealable manner and is movable between a rest position inside the casing 2 and an operating position in which the video projector 14 at least partially protrudes outside the casing 2.
According to one embodiment, the position and/or orientation of the video projector 14 is adjustable, for example by means of the electronic control system 10.
Similarly, the position of the display area 15 (or in other words the position of the display) is adjustable, for example by means of the electronic control system 10.
The appliance 1 or video projector may comprise a sharpness detector and/or a focus detector, e.g. an optical sensor, and be configured to perform auto-focusing on the basis of a sharpness or focus signal generated by the sharpness detector or focus detector.
The control system 10 may also be configured to visualize an alarm or alert by means of the video projector 14 directly at the components involved in the alarm or alert (e.g. door 18, auxiliary door 19, detergent drawer, filter holder), preferably in response to an anomaly signal provided by the anomaly detector 9, or in response to an instruction insertion signal 16 provided by the instruction insertion sensor 16, wherein the components or number for detection/monitoring fall within the detection range of such detector/ sensor 9, 16.
For example, the alert or alarm visualization may include one or more of the following alerts or alarms:
"component displacement" alerts, for example, that the door is open in the case of improper closing of the doors 19, or that the detergent drawer is removed in the case of incomplete insertion of the detergent drawer,
"missing part or substance" or "inserted part or substance" warning, for example, "filter change" in case the filter is missing or needs to be changed, or "detergent fill" in case the level of treatment substance is below a minimum level.
According to another embodiment, in addition to the visual operation of video projector 14, user interface 19 or video projector 14 may include an audio interface 51 controlled by electronic control system 10 to sound an audible alarm (e.g., sound, voice) and possibly audibly clarify the displayed information.
In the case of multiple projectors 14, the features described with reference to the video projector 14 apply to at least one, some or all of the video projectors 14.
Detailed description of the instruction insertion sensor 16
